Hi, I have a Sharp XE-A212 Cash register, and after knocking some buttons, I now have the issue where if I push a button, I just get the message "Not assigned."
The only actions I can now perform are Printing the last receipt, feeding paper, and pushing numbers. NO other keys work.

Hello,
it depends which model of the scanner did you purchase. As there are several models available, see below:
MS3780-9 OCIA and RS232 Transmit/Receive
MS3780-11 RS485 and Full RS232
MS3780-38 RS232 Low Speed USB*, Keyboard Emulation Mode or USB Serial Emulation Mode
MS3780-40 Full Speed USB
MS3780-41 RS232/Light Pen Emulation
MS3780-47 Keyboard Wedge, Stand-Alone Keyboard and RS232 Transmit/Receive
MS3780-48 Stand Alone Keyboard and RS232 Transmit/Receive
MS3780-120 USB and RS232 Transmit/Receive with EAS
As I checked the Sharp cash register, there are 2 RS232 connectors. So you probably have the MS3780-38, MS3780-48 or MS3780-120 model of the scanner.
To connect the scanner with RS232 interface of the cash desk please use the cabel 53-54000-3. You would also need a power supply. Im not sure in which country do you want to use the installation, so please select the right model for region from the list below:
AC to DC Power Transformer - Regulated 5.2VDC @ 1A output.
46-00525 90VAC - 255VAC United States, Canada and Japan
46-00526 90VAC - 255VAC Continental European
46-00527 90VAC - 255VAC United Kingdom
46-00528 90VAC - 255VAC Australia
46-00529 90VAC - 255VAC China
46-00530 90VAC - 255VAC India
I hope it helps.

Firstly, press subtotal (ST) button. If a price appears, you are in a sale and it is waiting for you to finish (try another method like credit). If it gives an error or beep when you press ST button and the drawer does not open when pressing CA/AT/NS, you probably haven't signed on. Try signing on using a PIN number (see clerk sign on in your manual)

Hi. Can you be more specific? What buttons are you pressing? Does it print at all?
